iOS Swift Development Table of Contents Overview When to Use Quick Start Reference Guides Best Practices Overview Build high-performance native iOS applications using Swift with modern frameworks including SwiftUI, Combine, and async/await patterns. When to Use Creating native iOS applications with optimal performance Leveraging iOS-specific features and APIs Building apps that require tight hardware integration Using SwiftUI for declarative UI development Implementing complex animations and transitions Quick Start Minimal working example: Reference Guides Detailed implementations in the references/ directory: Guide Contents --- --- MVVM Architecture Setup MVVM Architecture Setup Network Service with URLSession Network Service with URLSession SwiftUI Views SwiftUI Views Best Practices ✅ DO Use SwiftUI for modern UI development Implement MVVM architecture Use async/await patterns Store sensitive data in Keychain Handle errors gracefully Use @StateObject for ViewModels Validate API responses properly Implement Core Data for persistence Test on multiple iOS versions Use dependency injection Follow Swift style guidelines ❌ DON'T Store tokens in UserDefaults Make network calls on main thread Use deprecated UIKit patterns Ignore memory leaks Skip error handling Use force unwrapping (!) Store passwords in code Ignore accessibility Deploy untested code Use hardcoded API URLs
